Ring Blower
A Ring Blower is designed to deliver clean, oil-free, and continuous airflow for both pressure and vacuum applications. With its compact design and high efficiency, it is widely used in aquaculture, wastewater treatment, pneumatic conveying, and packaging machinery. Built using aluminium die-casting, the blower ensures durability, reliability, and quiet operation even under continuous duty.
Side Channel Blower
The Side Channel Blower operates on the side channel principle, where air is drawn in and accelerated multiple times within a specially designed channel before being discharged. This results in a steady, pulsation-free airflow. Its ability to generate both pressure and vacuum makes it highly versatile for applications in medical equipment, laboratories, printing, and industrial automation.
Turbine Blower
Known for its impeller-based turbine design, the Turbine Blower provides high pressure with consistent performance. It is ideal for industries that require continuous airflow with minimal noise and vibration. With its oil-free operation and low maintenance needs, it offers a reliable solution for applications such as drying, suction, aeration, and dust collection.
Regenerative Blower
A Regenerative Blower uses the principle of regenerating air multiple times within the impeller blades to achieve higher pressure and vacuum levels compared to standard fans or blowers. Its long service life, energy efficiency, and robust aluminium construction make it suitable for demanding environments like wastewater aeration, pneumatic conveying, and industrial processes.

Blower Operating principle
Ring Blower Operating Principle
A Ring Blower, also called a Side Channel Blower or Regenerative Blower, is an advanced machine designed to handle both vacuum and pressure applications with exceptional reliability. Unlike traditional compressors or vacuum pumps, a ring blower works on a unique side channel compression principle, which ensures continuous, pulsation-free airflow.
1
Air Intake
Ambient air enters through the inlet port.
2
Impeller Action
The impeller, fitted with multiple radial blades, rotates at high speed. Using centrifugal force, it throws the air outward.
3
Side Channel Compression
Instead of leaving immediately, the air is forced into a circular channel (the “ring”) where it repeatedly circulates between the impeller blades and the channel wall. With each circulation, the air pressure and velocity increase step by step.
4
Smooth Discharge
Once the required pressure or vacuum level is reached, the air exits through the outlet port, resulting in a steady and pulsation-free flow.
